I like to call this stage, "White Rain" (the opposite of the name of stage 2 - "Black Rain.") It's stage 2 but the ground / floor looks like snow -- pure white.

Note: [This image was not edited]

-I call it "hidden"(in heavy quotation) because of the fact that it is hidden. You won't be able to see this stage if you just enter numerical values within the limit / range of the startup window. (example: texture 0 = maximum, 3 = minimum)

Okay, I know what you're thinking of right now... like "How did he do that? / How do I do that?" or "Is that possible?"

So if you're curious or whatever you are... you can reveal this stage (I'd like to say unlock but unfortunately it's not locked ) by doing this:

WARNING: Putting in -2, -3, and so on... will cause the program to crash (one-time)

-Alright, that's it for revealing the "hidden" stage. (can't seem to find a more suitable word for it ) [and also, the word "hidden" seems to stir curiosity ]
-The stages 1 and 4 also look whitish but I chose stage 2 - Black Rain as the subject because the opposite color of the stage is white, hence, "White Rain".
-And for me, it's the most tolerable stage in lowest qualityamong the rest.

As for the lowest settings...

Some of you may know that (3) is the minimum number for the texture quality but unfortunately it's not

I tried to play around with the settings and found out that:
-1 is the lowest quality in the game, if you're extremely desperate you can use this.

Okay, if you already saw the "-1" quality (lowest) but didn't like it, you can also try the 2nd lowest in the game (8).
These are samples of texture quality "8."

Stage 1

Stage 2

Stage 3

Stage 4

Alright, that's it for now, if you ever discover something new regarding texture quality, feel free to post it here. )

EDIT: hehe, tryed it, it wasnt lagging extremly but it was still lagging, but it was playable, i now know why it lags ^^ when i picked up a summon ticket about 10-15 bots spawned over me and the lagging began... can that be fixed >.>?
